BEAN-VINE CUTTER.

o all 'it concern."

'Be ylt'known that LJos'EPH FRITSCHE, a

citizen Vof the United States, 4residing at.

Puente, in the. county of Los Angeles and `State of California, haveinvented new and useful Improvements in Bean-Vine Cutters, of .whichvthe following is a specification.

My invention relates to'harvesting lmachineryandespecially to bean vinecutters.

My object is to `make a bean vine cutter having tw'cutting bladesswinging to and from each other, and provide means for imparting aluniversal movement to each blade froma single handle for each blade.

A further object of my invention is to provide a bean Vine Ycuttercapable of wide manipulation as required for use upon rough ground. .4

Another object of my invention is to provide a bean vine cutter which issimple, durable, and easily operated, and not liable to get outof'order.

Other objects will appear hereinafter.

They drawings illustrate the invention.

' Figure 1 is avperspecti've ofabean Vine cutter embodying theprinciples of my invention. Y

7.,'llhewrunners,1 and u2.are cut from boards such as two by four or twoby six scantling, and each runner has a shoe 3 of strap iron turned upat itsforward end. Metal straps 4, 5, 6 and 7 are secured vertically attheir lower ends to the inner faces of the runners and said straps areinclined inwardly from the upper edges of the runners. Metal straps 8,9, 10 and 11 are secured against the outer faces of the runners intransverse alinement with the inner straps, said straps being held bybolts or rivets 12 passing through the outside straps and through therunners and then through the inside straps. The upper ends of the straps4, 5, 6 and 7, and the straps 8, 9, 10 and 11 are bent horizontallyinwardly and in alinement, and the beams 13 and 14 are mounted uponthese bent upper ends and secured by bolts or rivets 15. Boards 16 and17 are mounted longitudinally upon the beams 13 and 14, one on each sideof the center, to form a platform. The tongue 18 is mounted on top ofthe rear beam 13 and under the forward beam 14 and extends forwardlybeyond the ends of the .runners and carries a Specification of LettersPatent. Patented Jan. 1', 1.918.A Application filed July 23, 1917..seriai No. 182,240. i i

A pintlefr 22 is rotatably mounted in they bearing 21 and has abifurcated head 23. The cutter blade 24 is mounted in the bifurcation ofthe head 23 and held in place by they pivot 25 so that the blade mayswing to and from the runner 1 in a horizontal plane and so that it mayrotate on the pintle 22. The edge 2G ofthe blade is toward the center ofthe frame. A tooth 27 extends downwardly-from near the longitudinalcenter of the blade, said tooth being flat in a longitudinal. directionso that it will cut into the ground as the machine moves for wardly.l Abearing bracket 28 is fixed tol theinner face of the runner 1 a shortdistance behind the beam 14 and extends in-` wardly. A lever 29 ispivotallyconnected to the bracket 28 by a pin 30 near its lower.

end so that the lever may swing in a transverse direction. A toothedsector 31 is fixed upon or formed integral with the upper end of thelever 29 and extends in a longitudinal direction. A clevis link 32 ishinged to the lower end of the lever 29 by a pin 33 extending in alongitudinal direction and is hinged to the blade 24 by a pin 34extending in a vertical direction so that when the lever 29 is vibratedtransversely the free rear endof the blade 24 is swung to or from therunner 1. The second hand-lever 35 is connected to the lever 29 by anangle bracket 36 carrying a pivot pin 37, said pin extendingtransversely so that the lever may swing longitudinally. An arm 38extends from the lower end of the lever 35 rearwardly, and an off-setlink 39 connects the rear end of this arm 38 to an angle link 40 by apivot pin, and the angle link 40 is connected to a bracket 41, extendingupwardly from the blade 24, by a pivot 42, so that a transverse and alongitudinal joint is produced between the link 39 and the blade 24. Thehandle 43 is formed upon the upper end of the lever 35 and a pawl 4,4carried by the lever 35 engages the teeth .45

of the sector 31, to prevent the blade 24 Y, v from swinging downwardlywhen .tl1e pawl is adjusted. A link 46n connects the pawl 44 to the grip4'( pivotally mountedfupon the handle 43, so that when the handle 43isrgrasped .and the grip 47 pressed toward'y the handle, the lever 35may be swung forwardly or backwardly to'raise 'or' lower thev l blade24. A keeper 48 is fixed upon the ou'terlfacefoffthe runner lA andlextends up-Y wardly, and a` toothedlrack 49' ispivoted to the lever- 29and slidingly mounted trans'- .verselyfandhorizontally through/'the'keeper 48,;there being teeth upon the lower edge of the-*rackl49 togr-ithe ykeeper vand hold theupper endof the ever- 29 from swinginginwardly:A A link 50 connects the 'toothedracl-f49fto the gripflpivotally'- mounted uponfthe'fopposite side 'ofthe handle 43 from theigrip 47, softhat when-thehandle 43'is grasped and' thefgrip 51-vpressed "toward the handlefthe rack49 is -raised vout of engage#ment'with-fthe"keeper 48 and jthe lever`29 maybe #swungtransverselyuponthe pivotl 30-` to Y-move the-'blade 24 toward or from the runner 1.In a similar manne-r the'blade 52 is mounted inside-'of the `runner "2vand' manipulated the handle 53.
